January 22nd North American 850MHz HSPA 3G Blackstone...

Saw this news story, does anyone know if it is credible? The NextG Service is on the 850MHz band which is the same as Rogers/Fido in Canada and Cingular in the US...if all this is true then one of these unlocked would be 3G Compatible in North America...Thoughts?

Well that would suck for me because about 3 hours ago I got an iPhone because I really needed 3g already I do ally of browsing and videos but I like the touch he better....

What is the exact issue with North America and the Touch HD? I thought HSDPA was fully supported in our continent under most major providers. Just curious as I'm looking at purchasing one in the future.

The Touch HD that is out now operates on UMTS 900/2100. Telstra in Australia and the North American providers (except T-Mobile) use UMTS 850.

hopefully it is just some software that HTC did. cuz we do have that option to change it to 850MHz 3G in the phone but just nothing happens to it. If a flash can fix it then it should be ok. EDGE for me is pretty fast anyways in Toronto most of the time.

850 mHz is just one of the 2 bands needed to work on US 3G. you also need 1900 . my understanding is one band is for upload the other for download. don't get me wrong, it would be fantastic if the Aussie version was fully capable on US networks. i'll believe it when i see it. heck, expansys even has a note saying they have to confirm the 850mHz 3G band.

850/1900Mhz....
could someone please explain the upload/download at different frequencies paradigm to me?

This is incorrect. With at&t you do not need both. With just 850mHz you will be more than fine.
Now with T-Mobile you would need both 1700 and 2100 not just 2100 or just 1700 both. Just more reason to hate T-Mobile.

I am ready to take the plunge and drop the $ for an HD. I also will switch my number back to at&t from verizon. I guessi cna say almost ready. I really dont want to spend $800 for no 3G

Does anyone know how hspa in Canada with Rogers/Fido works? i.e. are dual frequencies required or is 850MHz enough to get top speeds? Thanks...

Has anyone brought one into the US and had any success getting a 3G signal ?

Some carriers in the US and Canada use 850mhz such as AT&T and Rogers but they also use 1900mhz. It really depends where you live... Whiich city, state etc
1900mhz is growing in popularity in the states.

Sadly, no 3G for me.

You do not need both 1900 and 850. Its only tmobile that u need both frequenes but they use 1700 and 2100. As long as u have ether 850 or 1900 (depending on what freuency ur area uses) u will have 3g with at&t.

No, the *network* you use may be present on more than one frequency, but its not 850 being uplink and 1700 being the downlink.
When we talk about UMTS the downlink is around 850/1700/2100 but the uplink is always a few MHz below that. (to be pedantic, the UMTS specification specifies the exact downlink/uplink separation)
I can't imagine HTC producing a UMTS 850 phone that won't work on ATT/Rogers and Telstra . Telstra only needs the 850 band so HTC can add in whatever extra the US providers use. It will probably be the same bands supported by the HTC Hermes and other phones common to these providers.

for AT&T, you do NOT need both frequencies (850 and 1900) for 3G. They don't HAVE both frequencies in most areas. It's one or the other.
And yes, T-Mobile US sucks ass...

Well I stand corrected then. This is good news then. Just need somebody in the US to buy a Telstra HD and see if it works. I guess it will be dependent on the area though. If you don't have 850mhz.

Lol i guess it took a senor member to say it for anyone to believe it. I only said it in the first page lol. Lets see what happens when the aus model comes out.

So it is decided then IF the Blackstone is introduced by Telstra and working on their 850MHz 3.5G Network THEN it has the opportunity to work in both the US on Att and Canada's Rogers/Fido...I will wait for this device, purchase it and let the board know if someone else doesn't beat me to it!
P.S. does someone think that this release may be with the Android OS for Telstra? It was the Telstra reps that were commenting at CES 2009 regarding Palm Pre and how the next Android phone that they were testing kicks it...who knows probably coincidence...

3G ATT (usa)?

not quite sure how to search this so i guess ill ask (or reask) the question.
1. am i able to reflash my Leo to work with USA ATT 3g bands if a rom ever comes out in the future?
2. can someone confirm to me if step #49 of this tips and tricks thread (http://forum.xda-developers.com/showthread.php?t=583638) and that piece of 3G activation software works and can allow my Leo to work with ATT 3g? (i dont think it does)
thanks!

1. Nope. It's all hardware.
2. See above. Nope.
It's all edge, my friend!

The HTC HD2 will not use 3g in the US. But since the phone is so fast, browsing the internet using edge is faster then with 3G on a sony X1a (my last phone).

do you already have an HD2? Regardless of anything you've read thus far, 3G is hardware dependent. No USA 3G internal radio? No USA 3G.
If you don't already have one, just wait until next month because the HD2 is supposedly coming to Telstra (who operates on 850mhz 3G, just like AT&T). HTC have said that the HD2 is coming in Q1 2010 but it's more than likely going toward T-Mo (based on leaked pics) or other carriers other than AT&T.

ah well i was under the impression that the hardware was both same for euro and us releases and just the software controlling it was different...(and how come they didnt name it the T8582 vs the T8585 as with the HD1 standard for the 2 different radios?....how they gonna distinguish the different hardware HD2s?)
come next year i may just sell mine for the new one (testra one you said). i dont suppose that tmo one will work with att 3g as its on a worldwide 3g band huh.
truly is a nice phone no doubt still

T-Mo US operates on 1700mhz AND 2100mhz for 3G (someone correct me if im wrong...one for uplink and the other for downlink). ATT can operate on 850mhz OR 1900mhz. The European version only has 900mhz and 2100mhz. As you can see, if you use the HD2 in the US (t-mo or ATT) right now, you're restricted to only EDGE unless they both possess their respective 3G bands.

this is what someone on htcforums.com said to me...confirm? deny? reject? love? i guess im just receiving conflicting info as to why this guy would believe this then?
"What you are asking about is a software differentiation. According to PDADB.net, the HD2 US version is scheduled for March 2010. http://pdadb.net/index.php?m=specs&id=2 ... us_htc_leo
The GSM version currently available is capable of T-Mobile US 3G frequencies; as T-Mo is the only US company to use WorldWide frequencies {2100MHz}. The version that is scheduled for March will be for AT&T frequencies. Since the hardware on these two versions are identical, you could flash a WorldWide version with a US version radio, & use a WW version with AT&T."

Your link doesnt work. I don't want to beat on a dead horse, but countless of T-Mo USA users have the HD2 and they could only have access to EDGE. Like I said, for T-Mo USA, their 3G has a split frequency (one for upload the other for download) that's why you need both 1700mhz and 2100mhz.

Europe: Network Bands
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
which means it can work here no? since USA att 3G is 850 or 1900?

* HSPA/WCDMA: 900/2100 MHz <--3G
* GSM: 850/900/1800/1900 MHz <-- EDGE

Your problem is that you're looking at the voice/2G/EDGE bands. The HD2 is a quadband phone, so you can pretty much use it anywhere in the world. Your original question was regarding 3G, which the HD2 does not support here in the USA (yet).
3G would be this line HSPA/WCDMA. See how it's only support 900/2100mhz?

GSM is only voice correct? .... getting my voice/data abbreviations all mixed up...

GSM is voice and EDGE (data)

For ATT the key is 850mhz 3G as that what ATT has been adding, I don't believe they are doing any new 1900 towers. You can bing it there are lot's of articles about the iPhone congestion and changing/adding 850 towers. If we are lucky Telstra an, Australian carrier, will pick up the phone soon because they use the same 850 just like ATT. This is how people got the 3G on the HD(1) to work on ATT in the united states. HTCPedia posted a Telstra HD2 rom on Dec 9th, so hopefully they are close to releasing.

HD2 and Nexus One on T-Mobile USA ???

Given the poor 3G coverage on T-Mobile in the US, why would two powerful phones such as the Nexus One and HD2 be relegated there? It is as if they are sabotoging themselves by being on T-Mob. (This paragraph was rhetorical).
My X1i is on it's last leg (screen blank in landscape and microphone not working) and I want to replace it. Currently, HD2 is the only thing that is appealing. I think I am going to hack one of the overseas models to work on 850MHz 3G on AT&T and forego waiting for the T-Mob model. Thanks XDA.
Hopefully, someone will make a step-by-step sticky on how to get the HD2 working on AT&T 3G USA.

1. Hard-SPL
2. Flash custom ROM
3. Insert SIM
That's what I did to get it working on Telus' 850mhz 3G. I remember the dude who made the huge thread about being the first in the US with a T9193 saying it was similarly easy.
If you just put your AT&T SIM in, you'll be able to send/receive texts, and make calls, but Telstra has the data connection settings locked down pretty heavily in the stock ROM...

OK, yeah, I was just looking through some of that thread. I thought it said something about changing or not changing radios. Is this already taken care of inside the custom ROMs ?

You need to make sure that the HD2 you buy has HSPA/WCDMA 850 MHz (not just GSM 850 MHz), because most do not.

Yes, based on what I am reading, getting the Telstra model with 850MHz 3G band should be compatible with 850MHz 3G AT&T in the U.S.
The designated-"U.S." model is designed for T-Mobile 3G (1700MHz or 2100MHz)

T-mobile's US HD2 works on 2100 MHz 3G in Europe?

Hi,
The official specs of T-mobile's HD2 says that the supported 3G bands are: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
Does it mean it will work on European 2100 MHz 3G too? Nexus one does so I suspect HD2 could too but as far as I could digg nobody had a straight answer to this question yet.
-AlefSin

actually i asked HTC CS before, and the answer is NO!
european countries WCDMA frequencies are the same with ASIAN countries. So no chance for European countries either.

hmmm I don't know JohnQ. In your attached email HTC is saying China's frequencies are different from the rest of the world so how do you say it's the same as Europe? I don't know much about 3G network in China though.

Just a few weeks back it was annoounced that the US operators had all signed up to migrating to the rest of the wold's GSM standards!
So in time we will all be singing from the same hymn sheet!

Accoridng to Wikipedia, while 3G in China is using the same frequencies as Europe in UMTS-I band, the air interface is different (TD-SCDMA vs TD-CDMA).

Wow, that's... odd! It seems US operators cannot even agree whinin US and now they all want to use the rest of world's standards! That's so un-american!

At&T, rogers, etc are all using european 3G frequencies, which is why you can use device from europe on their networks.
T-mobile US uses 1700 & 2100 (one for up stream, one for downstream) which is why it won't work on at&t etc or european frequencies.
The t-mobile 3G phones use both 1700 and 2100 at the same time; and they cant use 2100 seperately on other networks.

erm att uses 850/1900,and very few operators use the same,none in Europe use these bands

Well, it seems the answer is negative. I asked HTC:
Hi, I'm very excited about HTC HD2 on T-Mobile USA. However there is a cruicial question taht I could not find an answer for yet: Should I get this phone, when I travel to Europe, can I use 3G? The specs say this phone will support AWS/2100 MHz UMTS. Since the 2100 MHz is the dominant frequency for western european 3G networks, does it mean this phone would work on their 3G networks? Nobody at T-mobile's support could answer me so I hope you could solve this mystery.

And they answered:
Thank you for contacting HTC Technical Assistance Center. I understand the importance in researching a phone before you purchase it. This is a unusual situation and one T-mobile may not have been experienced with. For T-mobiles network the phone will be using the 1700 and 2100 bands. Although the 2100 band is common world wide. allowing the phone to pick up the edge network. T-mobile uses the 1700 for there 3G services. This band as far as we are aware is only used by T-mobile when it comes to major carriers world wide. More then likely the phone would not be able to pick up 3g if taken over seas.
However. T-mobile dose have a few branches in Europe. You may wish to check with them to see what bands they use for 3G, and if they have had any conflicts with American phones.

OK things are starting to get weird. I received a negative answer from HTC's customer support but then I found USA T-mobile G1 users that reported their phones were working on 2100 MHz 3G in Europe (G1 like US T-mobile version of HD2 only supports 1700/2100 MHz 3G). I need to buy a phone and these contradictory reports leave me confused

Here is what T-mobile says in the specs sheet of the new HD2:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

nice email address you have in that picture John

I tested my unlocked TMOUS HD2 in Sweden using 3's network and worked like a charm in 3G

Bit of a bump here as I'm trying to use my unlocked US T-Mobile HD2 with Orange in France and I can't do better than Edge (it went down to GPRS at one point...). I guess it could come down to spotty reception but I do get 3G speeds in my current location with an iPhone 3GS so I'm not so sure...
I'm using the AmericanAndroid ROM, maybe that's why my speed is throttled ;-)

I am using HD2 T-mobile in Serbia and i have no problem with conection or data speed.
I was on vacation and i didnt use Wifi ,and i used the phone all the time on 3G - the 3G network is incredibly fast, I even think that it is twice as fast as the EU HD2, which I used before..

Thanks, will check again then, maybe bad reception then!

Unlocking 3G on HTC Desire

I purchased an HTC Desire to use with my AT&T service. My Desire is GSM/WCDMA and not GSM/UMTS. Meaning, that my Desire can not run on anything but EDGE. I spoke with a rep at HTC and he let me know that there may be an APP to unlock the 3G service... Does anyone have any information on this?
Thank you kindly in advance...
~HR

isn't WCDMA = UMTS?

That's what I thought too, but the HTC rep, let me know that I can only unlock 3G with an App. That because I have an import and it's not currently available in the U.S. I would need to find this app and unlock my 3G service. The Desire wont pick up AT&T's 3G...

Yes........

I think it might be a frequency issue.
As far as I'm aware there are two models of Desire - A8181 and A8183.
In Australia, the model is the A8183 which provides WCDMA/UMTS at 850 and 2100 mhz. I think the A8181 operates at 900 and 2100 mhz.
If you imported from anywhere else other than Australia you'll most likely have a model A8181.
What frequency is AT&T 3g?

I do have an A8181. AT&T currently uses 850 and 1900 mhz...
Do you think there is a fix for this like the HTC rep mentioned?

AT&T uses 850/2100 like Telstra does in AU.
If you have the A8181 you are stuck with 900/2100. I think it's a hardware thing so an app probably wont help, not 100% sure about that though.

You bought the wrong phone ?(A8181)! As has been previously mentioned, you need an Australian Telstra Desire (A8183) to support AT&Ts 3G.
There is nothing that can be done about this because the hardware is different. You should sell your A8181 and buy an A8183.

Sorry to say , but I don't think so. the differences are in the hardware, not software.
You could always keep your device and change carrier? I presume someone in your area might use 2100 mhz??

Unfortunately not - the only other major GSM operator in the US is T-Mobile, and they use a split band of 1700/2100 and requires support for both to work.
